PCB probe test clamp

It is not recommended to copy, the cost is slightly higher, and the installation is also a bit troublesome. It is only for reference.

Due to issues with the leverage ratio and compression spring force, this test clamp can only accommodate 3-8 probes.

installation steps:

 1. Split and polish

2. Welding bracket

In order to ensure that the upper and lower plates are aligned, assemble them first and then weld them (of course, individual welding is no problem).

3. Welding probe cover

 First use a 3mm tap to tap the 2.5 hole base plate

Place the probe cover and tighten the screws (because the positioning points on some probe covers are randomly marked, directly inserting the probe will damage the probe, so it needs to be preprocessed with a 1.3mm drill bit)

Welding pin header and female header

4. Install the spring (warm reminder: please wear goggles to prevent the spring from hurting your eyes)

Two rotating shafts are needed here, one is used for fixation

5. Installation completed
